• ACTION: Final rule. January 12, 2004 Amendments to Standards of Performance for New Stationary Sources; Monitoring Requirements

SUMMARY: This action promulgates Performance Specification 11 (PS-11): Specifications and Test Procedures for Particulate Matter Continuous Emission Monitoring Systems at Stationary Sources; and Procedure 2: Quality Assurance (QA) Requirements for Particulate Matter Continuous Emission Monitoring Systems at Stationary Sources. The PS-11 and QA Procedure 2 will apply to sources that are required under an applicable regulation to use particulate matter continuous emission monitoring systems (PM CEMS) to monitor particulate matter continuously. The PS-11 and Procedure 2 will help to ensure that PM CEMS are installed and operated properly and produce good quality monitoring data on an ongoing basis.

• ACTION: Final rule. January 22, 2004 Revisions to Clarify the Scope of Certain Monitoring Requirements for Federal and State Operating Permits Programs; Final Rule

SUMMARY: This action ratifies certain current language of the state and federal operating permits program rules under Title V of the Clean Air Act concerning monitoring and declines to adopt the changes to the regulatory text of the monitoring rules that were proposed on September 17, 2002. EPA also announced a different interpretation of the “umbrella monitoring” rules (40 CFR 70.6(c)(1) and 71.6(c)(1)) from that set forth in the preamble to the proposal.
